AMPLIFIER
Any audio amplifier can be used with the LFT-11. The minimum recommended
amplifier power rating is 10 watts RMS per channel. We do not believe any built in
amplifier that is included on an internal sound card has sufficient amplifier power to drive
the LFT-11 to useable levels directly without the use of an external amplifier. The Radio
Shack Optimus STA-300 amplifier included with the LFT -11 is rated at 15 watts RMS
per channel and will drive the LFT-11 to suitable levels for most situations. Any other
power amplifier or receiver can be used with the LFT-11 with a RMS power rating of
between 10 and 50 watts per channel.
USING THE LFT-11 AS A HOME STEREO SYSTEM
Although the LFT-11 can fill a room with sound, this is not what the speaker is
designed for. The same characteristic that gives the LFT-11 superior performance as a
close up on axis speaker causes limitations in sound quality off - axis. Because the planar
panels are purposely designed to be very directional, their off - axis high frequency
response rolls off quickly and the overall frequency balance of the speaker will change.
When you are not directly in front of the speaker, the low frequency output of the speaker
will be emphasized and high frequencies will be lost. You can use the tone controls to
compensate for this somewhat to get a satisfactory off axis performance.
THE LINEAR FIELD TRANSDUCER
Eminent Technology's Linear Field Transducer, introduced as the LFT, represents
a new approach to the design and construction of a high-quality multimedia loudspeaker*.
It builds on the strengths of previous planar designs while eliminating many of their
drawbacks to allow use with computers.
